I am so thankful to you guys coz my 05 LS430 developed the same creaking sound and it was so annoying. The cabin used to be so quiet but the sanctuary was lost after rear left door/window seemed to be creaking. I bought some silicone spray yesterday and geneously applied to the door rubber and window seals and the creaking is all gone. I am so :) . Now i wonder was it the door or the window or both. I suspect it was the window. Will see if it develops again and try to narrow it down to door or window. Thanks once again.

I have a 2005 LS 430 with 25K miles. It has heated/cooled seats which seem to work but not as I would expect them too. The heating part if fine I guess because it uses electric filament and no fan or air. I say this because the fan in seat turns off when you move the knob to heater position. The problem is seat cooling. I have cleaned the seat filters thoroughly and still no good. They feel a little cooler after 10 minutes but then it feels the same again. I checked fuses and the fan and they all are fine. You can hear the seat fan running and you turn it on. I am not happy with them. I drove a 2006 GS350 and a 2007 IS 250 which cooled seats and oh man they chill your !Removed! like you are sitting on ice. You have to set them to 1 or 2 as 3 would make you cold. In my car even at 3 feels like nothing. I examined in the 07 IS250 that their seat fans are big and I did not notice any filter. My last option is to replace the seat filters which are not in bad shape at all (only 25K miles) The filters cost $97 a piece at a dealer and $57 a piece at Sewell Lexus. www.beta.lexus-parts.com part # PART # 88921-50010. I want to know how your cooled seats work on LS 430. have you had any problems with cooling ? Compared to GS350 and IS250 my climate seats don’t cool at all :(

It happens every morning and the car will sit overnight in the parking garage. The slope is towards the left side and very little one. I would say may be 3-5 degrees. The car does not sit more than 12 hours at night. I have a feeling its related to my oil change to Mobil 1. But this noise stays for 10 minutes and vanishes completely when engine is warm. It comes back again if the car sits for 5 hours like in my office and does not cool down completely. I use OEM Toyota filter. The one that ends in D3. It has Mobil 1 5w-30 in it now. It does not seem to be an injector problem as i dont move the car once its parked. Does it take 5 minutes for OEM filter to fill up???? The noise stays till engine has reached middle point on the coolant guage. I cannot go back to dino oil to see if it is the oil because i think its no recommended at all..... what else can I test ? Is it piston slap coz they expand when engine gets hot ???? This noise is best described as " When you turn on the engine and it idles, there is a faint noise that comes from inside the engine compartment when the belts turn...like a constant "shook, shook, shook" but not extremely loud can notice it only when idling and when driving slow speeds...at higher speeds engine runs smooth... " I copied this line from http://www.automotiveforums.com/t252138-ne...0_miles___.html but this guy has much more severe problems than me. My Ls430's engine is clean and no problems what so ever except this annoying noise which haunts me in my sleep toooo :( as i am a perfectionist or at least try to be and even a little thing bothers me :( Thanx NC211 what else can you suggest .....

I have a 2005 LS430 that i bought a month ago. it has 25K miles. I switched from dino oil to Mobil 1 at last oil change. I recently noticed an engine noise which comes when engine is cold and goes away when its warm. Its not loud but it is annoying to me. The noise is like "shook shook shook shook" and seems like something to do with a bearing or pulley on low Rpm when cold. It goes away magically when engine is warm. It is more noticable in parking garage or when windows open. I tried turning AC on and off thinking its compressor but to no avail. I hate this noise and i know its not Lexus like. When warm, its very quiet. i have tried to listen where the noise comes from but to no avail. It does not seem like EGR/Valve/lifter noise. I took it to dealer and left overnight to look for this noise. Next morning they started car in front of me and it did not even come that day. Also noticed this noise come when car is parked on a little slope. The noise is lesser if car parked on a flat surface overnight. Something to do with oil or pump ? i am going nuts.... Please help :)
